Fix wrong constant usage in go mate

Fixes an oversight in https://github.com/official-stockfish/S ... /pull/5094

In theory, master could stop search when run with `go mate 247` and return a TB loss (not a mate score). Also fixes the spelling of opponenWorsening.

Many thanks.

It’s seems that it’s not a good and reliable version. I haven’t test it yet.

Thanks Cengiz-Baba for your tests. (Three tests )Totally super strong engines should practice more with black pieces. They are not good players with black.

You're Welcome Homoyoun.

I do this on purpose and I use UHO test suite. Because a duel with a low DrawRatio will be bloody. Engines behave very differently with games between +0.90 and +1.0 and it becomes easier to compare engines.

Best regards, Fringe.

Please Cengiz, could you share that UHO pgn test, only that are you using to test and please...how many plies hoy are using in Depth?
